Study: Vitamin D3 Prevents Flu Better than Vaccines/Anti-virals

An important new study was released in the American Journal of Clinical Nutrition in May 2010 showing Vitamin D3 is more effective in preventing flu than vaccines and antivirals. Cod liver oil is my choice for a natural ratio of D3 and A along with the good oils. One should wonder why the public health authorities and the CDC do not recommend Vitamin D3 to prevent flu and other disorders? As the ad shows, it has been known for a long time and recommended by doctors everywhere.

The abstract is here, but the article appeared in the UK Times. Here are some extracts:

Vitamin D better than vaccines at preventing flu, report claims

The risk of children suffering from flu can be halved if they take vitamin D, doctors in Japan have found. The finding has implications for flu epidemics since vitamin D, which is naturally produced by the human body when exposed to direct sunlight, has no significant side effects, costs little and can be several times more effective than anti-viral drugs or vaccine.

Only one in ten children, aged six to 15 years, taking the sunshine vitamin in a clinical trial came down with flu compared with one in five given a dummy tablet. Mitsuyoshi Urashima, the Japanese doctor who led the trial, told The Times that vitamin D was more effective than vaccines in preventing flu.

The Japanese scientists, writing in the American Journal of Clinical Nutrition, say that the anti-viral drugs zanamivir and oseltamivir reduce risk of flu infection by 8 per cent in children who have been exposed to infection, compared with a 50 per cent or greater reduction with vitamin D.

Anti-virals are also too expensive, and possibly too toxic, to be given to the population as a whole whereas vitamin D has additional benefits. The sunshine vitamin not only prevents bone fractures but is also believed to reduce risks of cancer, heart disease, diabetes and other illness, including various bacterial as well as viral infections.

Vitamin D3 has long been known as a preventative and in building natural immunity. Also, a D3 deficiency is common and may affect most people due to poor diet and lack of animal fats.

A recent original article by Raine Saunders, a Journal correspondent, covers Vitamin D and provides terrific links for more information on treatment and prevention of all types of disorders.

  1. We should wonder? They don’t get kickbacks from the folks who produce vitamins!

    It should become criminal to allow the drugs/vaccines to pay the CDC, FDA & docs the way they do in order to keep info like this from the public (unless they are looking for the info).

  2. Sunbath or exposure to sunlight daily for about 10 to 15 minutes,
    is said to be sufficient for human body to produce enough Vitamin D
    for its daily needs.

    • Partly– there are D3 absorption inhibitors and well as lack of animal fats that may limit d3 production. So 10-15 min in the sun could still be inefficent. Plus it says D3 is 7 times more effective than the antivirals mentioned. Plus, at least 50 studies show flu shots do not work for any age group.

  3. If you are in the Northern Hemesphere, north of the 33rd Latitude the suns rays are not strong enough to give you enough D. We are left to supplementation. Finding safe and effective supplements can be frustrating. May I help you with that?

  4. With the fall and winter coming here in NYC i’m getting ready to take my Fermented Cod Liver Oil daily in the mornings. Over the summer i was taking two pills of it too but trying to get at least 20 minutes of direct sun-exposure, too. With the fall and winter i suppose i’ll up the FCLO. Sound good?

  5. Most of the research points to numerous benefits of vitamin D and that most Canadians don’t get enough year round, even with increased sun exposure in the summer months. The list of conditions that vitamin D can help prevent continues to grow including breast and prostate cancer, osteoporosis, insulin resistance, multiple sclerosis and cold and flu. Check with your naturopathic doctor about how much vitamin D is appropriate for you.

    • Thanks Pamela. I did not know you were a reader. D3 acts also like a hormone I have read. Yes, get a blood test and have the doctor suggest the source. The Bitotin drops are much higher than cod liver oil— if it is indicated

    Scientists have found that many cells in the body have Vitamin D receptors, including the breast and prostate. But, from what I understand of cell biology, vitamin A ( preformed, not from plants) is required to get the vitamin D into its receptors. Chris Masterjohn often writes about vitamins A and D on his blog, but otherwise it is difficult to find anything on the web. You have to dive into a cellular biology text. That is why cod liver oil is such a good form of vitamin D, because it also contains vitamin A. Large amounts of D without A can be, and will be toxic. If you are taking large amounts of Vitamin D, and dont notice an appreciable rise in your D levels, this may be a factor.

    It is very important to get the appropriate form — Vitamin D 3 is the vitamin you need. Some soy and rice milks contain D2 (produced by invertebrates and mushrooms), but his form is not absorbed properly by the body and may cause excess deposition of calcium in soft tissues, such as arterial walls.

    • We really want you to write something as a guest blogger, an article on nutritional healing –actually on Fluoride in city water–maybe, Sylvia.
      It would seem blood levels and cell penetration would be two different measures possibly. I heard if you have a natural ration of D/A, as in CLO, is optimal absorption through the gut. Also, Sylvia– do you know what makes fermented CLO much better yet?

  7. I am very encouraged to see research like this coming to light and being seen by people. It is so important for people to realize the power of foods containing Vitamin D (cod liver oil, pastured meats, meat products, safe seafood, and dairy products) rather than relying on a broken system (western medicine) to solve these problems, because conventional medical wisdom has fallen short on that score. Augie is right – get your levels tested if you are wondering. So many people are deficient, it’s probable that most everyone needs to be consuming large amounts of a natural food which contains these essential nutrients which are actually hormones. Thanks for this post, Augie!

  8. Ironic that this ad was displayed right below the D3/flu article…hmm:

  9. Does no one else find it self-serving that this website completely ignores the last two paragraphs of the UK Times article where the lead scientist for this study, Dr. Urashima, and another virologist actually advocate using both Vitamin D3 AND vaccines together for maximum protection?

    “Dr. Urashima said: ‘Vitamin D and vaccine work by quite different mechanisms. Vitamin D enhances innate immunity while vaccine enhances acquired immunity. So we do not have to select only one way of prevention, rather we should do both ways, I think.'”
